IMPORTANT SAFEGUARDS

Follow all warnings and instructions marked on this television receiver.

CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER

(OR BACK). NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO

QUALIFIED SERVICE PERSONNEL.

The lightning flash with arrowhead symbol, within an equilateral triangle, is intended

to alert the user to the presence of uninsulated "dangerous voltage" within the product's

enclosure that may be of sufficient magnitude to constitute a risk of electric shock to

persons.

The exclamation point within an equilateral triangle is intended to alert the user to the

presence of important operating and maintenance (servicing) instructions in the literature

accompanying the appliance.

WARNING:

TO PREVENT FIRE OR SHOCK HAZARD, DO NOT EXPOSE THIS TELEVISION TO

RAIN OR MOISTURE.

• There are no user serviceable parts inside the receiver.

• Never remove the back cover of the TV set, as this can expose you to a very high

voltage and other hazards.

• If the TV set does not operate properly, unplug the set and call your dealer or service

shop.

WARNING:

POWER SOURCE:

 This TV set operates only on AC 120 volts 60 Hz.

 To prevent fire or shock hazard, connect this TV set to 120V AC 60Hz (house current)

ONLY. Never connect the TV to 50 Hz or DIRECT CURRENT POWER SOURCES.

 This TV set is equipped with a polarized alternating current line plug (a plug having one

blade wider than the other).

This plug will fit into the receptacle only one way.

If you are unable to insert the plug fully into the receptacle, try reversing the plug.

If the plug should still fail to fit, contact a local electrician.

 To prevent shock hazard do not use this polarized plug with an extension cord,

receptacle or other outlet unless the blades can be fully inserted to prevent blade exposure.

 If the power cord or plug is damaged or frayed, unplug the TV set from the receptacle

and refer servicing to qualified service personnel.

 To prevent fire or shock hazard, do not overload receptacle and extension cords.

• POLARIZED PLUG

• NO GOOD

INSTALLATION

 ANTENNA

Unless your TV set is connected to a cable TV system or to a centralized antenna system,

a good outdoor color TV antenna is recommended for the best performance. However, if

you are located in an exceptionally good signal area that is free from interference and

multiple image ghosts, the indoor antenna may be sufficient.

 LOCATION

Select an area where sunlight or bright indoor illumination will not fall directly on the picture

screen. Also, be sure that the location selected allows a free flow of air to and from the

perforated back cover of the TV set.

To prevent damaging the TV, do not leave the set in a place where the temperature

becomes too hot. For example, exposed to direct sunlight or near a heating device, etc.

 VIEWING

This TV set may be viewed from any desired distance. Most viewers prefer a distance of

three to six feet or more, depending on screen size, for maximum eye comfort.

where the

power cord is subject to traffic or abuse. This may result in a shock or fire hazard.

5 Do not attempt to service this television set yourself as opening or removing covers

may expose you to dangerous voltage or other hazards. Refer all servicing to qualified

service personnel.

6 Never push objects of any kind into this television set through cabinet slots as they

may touch dangerous voltage points or short out parts that could result in a fire or

electric shock. Never spill liquid of any kind on the television set.

7 If the television set has been dropped or the cabinet has been damaged, unplug this

television set from the wall outlet and refer servicing to qualified service personnel.

PROTECTION AND LOCATION OF YOUR SET

16-1 If an outside antenna is connected to the television set, be sure the antenna

system is grounded so as to provide some protection against voltage surges and built

up static charges, Section 810 of the National Electrical Code, NFPA No. 70-1975,

provides information with respect to proper grounding of the mast and supporting

structure, grounding of the lead-in wire to an antenna discharge unit, size of grounding

conductors, location of antenna discharge unit, connection to grounding electrode, and

requirements for the grounding electrode.

Click to see antenna grounding diagram.

16-2 Note to CATV system installer: (Only for the television set with CATV reception)

This reminder is provided to call the CATV system installer's attention to Article 820-40

of the NEC that provides guidelines for proper grounding and, in particular, specifies

that the cable ground shall be connected to the grounding system of the building, as

close to the point of cable entry as practical.

17 An outside antenna system should not be located in the vicinity of overhead power

lines or other electrical lights or power circuits, or where it can fall into such power lines

or circuits. When installing an outside antenna system, extreme care should be taken to

keep from touching such power lines or circuits as contact with them might be fatal.

18 For added protection for this television set during a lightning storm, or when it is left

unattended and unused for long periods of time, unplug it from the wall outlet and

disconnect the antenna. This will prevent damage due to lightning and power-line

surges.
